"In the heart, there's a strange object?"
When Chu Fengmian heard Xing Xuan's words, he suddenly realized that there indeed was a pure essence of life force within the Heart of Blood Evil Demon Emperor.
This particular life force has been sustaining the vitality of the Blood Evil Demon Emperor's heart.
Previously, this life force should have been suppressed by the Tai Chu Sword Edge, which is why it couldn't manifest.
Now that Chu Fengmian had extracted part of the Tai Chu Sword Edge, the potent life force within the Blood Evil Demon Emperor's heart was starting to facilitate its gradual resurrection.
Even the wounds on the Blood Evil Demon Emperor's heart were being slowly repaired; though slow, Chu Fengmian sensed that once these wounds were completely healed, it would be the day of the Blood Evil Demon Emperor's rebirth.
That moment would signify a genuine catastrophe.
"What exactly is this thing?"
